Ein derartiges Motorrad ist aus der DE 37 08 579 A1 bekannt. Zum technischen Hintergrund der Erfindung zählen die US 4 179 135 , US 3 549 167 , DE 90 13 180 U1 sowie die DE 102 45 983 A1 .Such a motorcycle is from the DE 37 08 579 A1 known. The technical background of the invention include the US 4,179,135 . US 3,549,167 . DE 90 13 180 U1 as well as the DE 102 45 983 A1 ,

Das Motorrad "K1200 S" von BMW weist eine Vorderradaufhängung auf, die unter der Bezeichnung "Duolever" bekannt ist. Kinematisch betrachtet ist die Duolever-Vorderradaufhängung ein Gelenkviereck, das durch zwei übereinander angeordnete, jeweils schwenkbar am Rahmen oder an einem Motorgehäuse gelagerte Längslenker gebildet ist. Vordere Enden der Längslenker sind jeweils über ein Kugelgelenk mit einem gabelartigen Radträger verbunden, der bei der K1200 S einteilig aus Aluminiumkokillenguss hergestellt ist. Die Federung und Dämpfung übernimmt ein Federbein, das am unteren der beiden Längslenker angelenkt ist und das sich gegen den Rahmen abstützt. Ein am "Steuerkopf" und Radträger gelagertes, trapezförmiges Scherengelenk ist mit dem Lenker gekoppelt und überträgt die über den Lenker eingesteuerten Lenkbewegungen auf den Radträger.The "K1200 S" motorcycle from BMW has a front suspension known as "Duolever". Viewed kinematically, the Duolever front suspension is a four-bar linkage, which is formed by two superimposed, each pivotally mounted on the frame or on a motor housing trailing arm. Front ends of the trailing arms are each connected via a ball joint with a fork-like wheel carrier, which is made in the K1200 S in one piece from aluminum chill casting. The suspension and damping takes over a shock absorber, which is articulated at the bottom of the two trailing arms and which is supported against the frame. A trapezoidal scissor joint mounted on the "steering head" and wheel carrier is coupled to the handlebar and transmits steering movements via the handlebar to the wheel carrier.

Aufgabe der Erfindung ist es, ein Motorrad mit einer Vorderradaufhängung, insbesondere einer so genannten "Telelever-Vorderradaufhängung", zu schaffen, die insbesondere in Bezug auf über das Vorderrad in den Radträger eingeleitete "Schlagkräfte", wie sie z. B. beim Überfahren von Hindernissen auftreten, einen noch besseren Fahrkomfort bietet.The object of the invention is to provide a motorcycle with a front suspension, in particular a so-called "Telelever front suspension", in particular with respect to the front wheel in the wheel initiated "impact forces", as z. B. when driving over obstacles, offers even better ride comfort.

Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.This object is solved by the features of claim 1. Advantageous embodiments and further developments of the invention can be found in the dependent claims.

Ausgangspunkt der Erfindung ist ein Motorrad mit einer Vorderradaufhängung, insbesondere einer "Duolever-Vorderradaufhängung", die jedoch nicht Bestandteil der vorliegenden Erfindung ist. Wenngleich die Erfindung im folgenden überwiegend anhand einer Duolever-Vorderradaufhängung beschrieben wird, sei ausdrücklich darauf hingewiesen, dass die Erfindung insbesondere bei der von BMW-Motorrädem seit langem bekannten so genannten "Telelever-Vorderradaufhängung" anwendbar ist, die sich durch eine Teleskopgabel auszeichnet, deren untere Gabelrohre über einen Längslenker gelenkig am Rahmen oder am Motorgehäuse des Motorrads abgestützt sind.The starting point of the invention is a motorcycle with a front suspension, in particular a "Duolever front suspension", which is not part of the present invention. Although the invention is described below mainly on the basis of a Duolever front suspension, it should be expressly understood that the invention is particularly applicable to the so-called "Telelever front suspension", which has been known for a long time by BMW motorcycles, and which is characterized by a telescopic fork lower fork tubes are articulated to the frame or motor housing of the motorcycle via a trailing arm.

Eine Duolever-Vorderradaufhängung weist einen gabelartigen Radträger mit zwei starren Gabelarmen auf, an denen ein Vorderrad des Motorrads gelagert ist. Bei dem Radträger kann es sich beispielsweise um ein Aluminiumgussteil handeln. Der Radträger ist mittels zweier schwenkbar übereinander angeordneter Längslenker am Motorrad aufgehängt. Hintere Enden der Längslenker können z. B. über Schwenkgelenke mit dem Rahmen bzw. mit dem Motorgehäuse des Motorrads verbunden sein. Die Längslenker sind zur Aufnahme von über das Vorderrad in den Radträger eingeleiteten Kräften vorgesehen und ermöglichen ein Ein- bzw. Ausfedern des Radträgers. Jeder der beiden Längslenker kann zwei Arme aufweisen, deren hintere Enden auf der linken bzw. auf der rechten Seite des Motorrads mit dem Motorradrahmen oder mit dem Motorgehäuse schwenkbar verbunden sind. Nach vorne hin laufen die beiden Arme eines jeden der beiden Längslenker zusammen und sind dort jeweils über ein Kugelgelenk mit dem Radträger verbunden.A Duolever front suspension has a forked wheel carrier with two rigid fork arms on which a front wheel of the motorcycle is mounted. The wheel carrier may be, for example, an aluminum casting. The wheel carrier is suspended by means of two pivotally superimposed trailing arms on the motorcycle. Rear ends of the trailing arm can z. B. be connected via pivot joints with the frame or with the motor housing of the motorcycle. The trailing arms are provided for receiving introduced via the front wheel in the wheel carrier forces and allow a compression or rebound of the wheel carrier. Each of the two trailing arms may have two arms whose rear ends on the left and on the right side of the motorcycle with the motorcycle frame or with the motor housing are pivotally connected. Towards the front, the two arms of each of the two trailing arms run together and are connected there via a ball joint with the wheel carrier.

Der Kern der Erfindung besteht in einer Telelever-Vorderradaufhängung, bei der das Kugelgelenk, über das der Längslenker mit der die unteren die Gabelrohre der Teleskopgabel verbindenden Gabelbrücke verbunden ist, elastisch mit dem Längslenker und/oder mit der zugeordneten Gabelbrücke verbunden ist. Ein Motorrad mit einer erfindungsgemäßen "Telelever-Vorderradaufhängung" weist also mindestens folgende Merkmale auf:

  • eine Teleskopgabel, mit zwei oberen und zwei relativ dazu verschieblichen unteren Gabelrohren,
  • eine Gabelbrücke, welche die beiden unteren Gabelrohre miteinander verbindet,
  • einen Längslenker, mit einem in Fahrtrichtung gesehen vorderen Ende, das über ein Gelenk (20) mit der Gabelbrücke verbunden ist, wobei das Gelenk elastisch mit dem Längslenker oder/und mit der Gabelbrücke verbunden ist.
The essence of the invention consists in a Telelever front suspension in which the ball joint, via which the trailing arm is connected to the lower fork legs of the telescopic fork connecting fork bridge, is elastically connected to the trailing arm and / or with the associated fork bridge. A motorcycle with a "Telelever front suspension" according to the invention thus has at least the following features:
  • a telescopic fork, with two upper and two relatively movable lower fork tubes,
  • a fork bridge, which connects the two lower fork tubes,
  • a trailing arm, with a seen in the direction of travel front end which is connected via a hinge (20) with the fork bridge, wherein the joint is elastically connected to the trailing arm and / or to the fork bridge.

Der Begriff "elastisch" bedeutet in diesem Zusammenhang, dass primär in Fahrtrichtung über das Vorderrad in den Radträger eingeleitete Schläge, z. B. beim Überfahren von Hindernissen, in gewissem Umfang "abgefedert" werden können, d. h. nicht völlig ungefedert vom Radträger über die Gelenke in die Längslenker und weiter in den Motorradrahmen bzw. das Motorgehäuse eingeleitet werden.The term "elastic" in this context means that primarily in the direction of travel on the front wheel in the wheel carrier initiated strokes, z. B. when crossing obstacles, can be "cushioned" to some extent, d. H. not completely unsprung from the wheel through the joints in the trailing arm and further into the motorcycle frame or the motor housing are introduced.

Ausdrücklich sei erwähnt, dass sämtliche nachfolgend beschriebenen Merkmale bzw. Merkmalskombinationen, welche die elastische Anbindung des Kugelgelenks bzw. der Kugelgelenke beim Duolever an den zugeordneten Längslenker bzw. an den Radträger betreffen, in konstruktiv gleicher Weise auch auf die elastische Anbindung des Kugelgelenks einer Telelever-Vorderradaufhängung anwendbar sind, bei der, wie oben beschrieben, die die unteren Gabelrohre verbindende Gabelbrücke über ein Kugelgelenk mit einem Längslenker verbunden ist, der wiederum gelenkig mit dem Rahmen bzw. mit dem Motorgehäuse des Motorrads verbunden ist.It should be expressly mentioned that all the features or combinations of features described below, which relate to the elastic connection of the ball joint or the ball joints in Duolever to the associated trailing arm or to the wheel carrier, in a structurally the same way on the elastic connection of the ball joint of a Telelever- Front suspension are applicable, in which, as described above, the the lower fork tubes connecting fork bridge is connected via a ball joint with a trailing arm, which in turn is pivotally connected to the frame or with the motor housing of the motorcycle.

Bei einer Duolever-Vorderradaufhängung ist vorzugsweise zumindest das Gelenk, über das der obere Längslenker mit dem Radträger verbunden ist, elastisch "angebunden". Wie bereits erwähnt, kann wahlweise zwischen dem Gelenk bzw. den Gelenken und dem Radträger oder/und zwischen dem Gelenk bzw. den Gelenken und dem jeweils zugeordneten Längslenker eine entsprechend in Längsrichtung des Motorrads elastisch gestaltete Bauteilverbindung vorgesehen sein.In a Duolever front suspension is preferably at least the joint, via which the upper trailing arm is connected to the wheel carrier, elastic "tailed". As already mentioned, optionally between the joint or the joints and the wheel carrier and / or between the joint or the joints and the respective associated trailing arm, a correspondingly designed in the longitudinal direction of the motorcycle elastic component connection can be provided.

Eine derartige Längselastizität kann z. B. mittels eines Federblechs erreicht werden. Alternativ oder ergänzend dazu können Elastomerelemente verwendet werden.Such longitudinal elasticity may, for. B. can be achieved by means of a spring plate. Alternatively or additionally, elastomeric elements may be used.

Figur 1 zeigt eine Vorderradaufhängung für Motorräder nach dem so genannten "Duolever-Prinzip". Eine derartige Vorderradaufhängung weist einen gabelartigen Vorderradträger 1 auf, der z. B. in Form eines Gussteils aus einer Aluminiumlegierung hergestellt sein kann. Der Vorderradträger 1 hat die Form einer Gabel mit einem linken Gabelholm 2 und einem rechten Gabelholm 3 an deren unteren Enden Lageraugen 4, 5 zur Aufnahme einer Achse eines Vorderrads (nicht dargestellt) vorgesehen sind. Im oberen Drittel des Vorderradträgers 1 sind die beiden Gabelholme 2, 3 durch einen Steg 6 miteinander verbunden. Die oberen Enden der Gabelholme 2, 3 laufen zusammen und sind einstückig miteinander verbunden. Der Vorderradträger 1 ist mittels eines oberen Längslenkers 7 und mittels eines unteren Längslenkers 8 an einem hier nicht dargestellten Rahmen des Motorrads schwenkbar gelagert. Der obere Längslenker 7 weist einen linken Längslenkerarm 9 und einen rechten Längslenkerarm 10 auf, an deren hinteren Enden jeweils ein Lagerauge 11 bzw. 12 vorgesehen ist. Die beiden Lageraugen sind über einen hinteren Quersteg 13 miteinander verbunden. An den Lageraugen 11, 12 ist der obere Längslenker 7 am Rahmen (nicht dargestellt) des Motorrads schwenkbar gelagert. FIG. 1 shows a front wheel suspension for motorcycles according to the so-called "Duolever principle". Such a front suspension has a fork-like front wheel 1, the z. B. may be made in the form of a casting of an aluminum alloy. The front wheel carrier 1 has the shape of a fork with a left fork leg 2 and a right fork leg 3 at the lower ends of bearing eyes 4, 5 for receiving an axle of a front wheel (not shown) are provided. In the upper third of the front wheel carrier 1, the two fork legs 2, 3 are interconnected by a web 6. The upper ends of the fork legs 2, 3 run together and are integrally connected. The front wheel 1 is pivotally mounted by means of an upper trailing arm 7 and by means of a lower trailing arm 8 on a not shown frame of the motorcycle. The upper trailing arm 7 has a left trailing arm 9 and a right trailing arm 10, at the rear ends of each bearing eye 11 and 12 is provided. The two bearing eyes are connected to each other via a rear crosspiece 13. At the bearing eyes 11, 12 of the upper trailing arm 7 on the frame (not shown) of the motorcycle is pivotally mounted.

Wie aus Figur 1 bzw. 2 ersichtlich ist, laufen die beiden Längslenkerarme 9, 10 des oberen Längslenkers 7 nach vorne hin zusammen und sind durch einen vorderen Quersteg 14 miteinander verbunden. Die beiden Längslenkerarme 9, 10 reichen noch ein Stück bis vorderhalb des vorderen Querstegs 14 nach vorne, was am besten aus Figur 2 ersichtlich ist. Im Bereich zwischen den vorderen Enden der Längslenkerarme 9, 10 ist ein Gelenkaufnahmeelement 15 mit einer Durchgangsbohrung 16 vorgesehen. Das Gelenkaufnahmeelement 15 weist auf seiner linken und seiner rechten Seite jeweils einen Schlitz auf, in den ein linkes bzw. rechtes blattfederartiges Federelement 17, 18 eingesetzt ist. Die blattfederartigen Elemente sind mit dem zugeordneten Längslenkerarm 9 bzw. 10 und dem Gelenkaufnahmeelement 15 verschraubt.How out FIG. 1 2, the two trailing arm arms 9, 10 of the upper trailing arm 7 converge towards the front and are connected to each other by a front transverse web 14. The two trailing arm 9, 10 are still a bit to front of the front crosspiece 14 forward, which is best FIG. 2 is apparent. In the area between the front ends of the trailing arm 9, 10 a joint receiving element 15 is provided with a through hole 16. The joint receiving element 15 has on its left and its right side each have a slot in which a left or right leaf spring-like Spring element 17, 18 is used. The leaf spring-like elements are bolted to the associated trailing arm 9 and 10 and the joint receiving element 15.

Wie am besten aus Figur 2 ersichtlich ist, sind die blattfederartigen Elemente 17, 18 so angeordnet, dass ihre Hauptebene, d. h. in Figur 2 ihre Stirnseite im wesentlichen senkrecht zu den Enden der Längslenkerarme 9, 10 bzw. parallel zu einer Querachse durch die beiden Lageraugen 11, 12 des oberen Längslenkers 7 ist. Dadurch ist das Gelenkaufnahmeelement 15 relativ steif in einer Querrichtung, d. h. parallel zu einer Querachse durch die Lageraugen 11, 12 mit dem oberen Längslenker 7 verbunden. Auch in Richtung der Längsachse der Durchgangsbohrung 16 ist das Gelenkaufnahmeelement 15 relativ steif mit dem oberen Längslenker 7 verbunden.How best FIG. 2 it can be seen, the leaf spring-like elements 17, 18 are arranged so that their main plane, ie in FIG. 2 its end face is substantially perpendicular to the ends of the trailing arm arms 9, 10 or parallel to a transverse axis through the two bearing lugs 11, 12 of the upper trailing arm 7. Thereby, the joint receiving element 15 is relatively stiff in a transverse direction, that is connected to the upper trailing arm 7 parallel to a transverse axis through the bearing eyes 11, 12. Also in the direction of the longitudinal axis of the through hole 16, the joint receiving element 15 is relatively rigidly connected to the upper trailing arm 7.

In Längsrichtung des Motorrads bzw. in Längsrichtung der Längslenkerarme 9, 10 hingegen ist durch die blattfederartigen Elemente 17, 18 eine gewisse Elastizität sichergestellt. In gewissem Umfang kann das Gelenkaufnahmeelement 15 also in Richtung der Längsrichtung der Längslenkerarme 9, 10 verschoben werden. In gewissem Umfang ist auch eine Verdrehung des Gelenkaufnahmeelements 15 um eine Querachse, die parallel zu einer Querachse durch die Lageraugen 11, 12 ist, relativ zum oberen Längslenker 7 möglich.In the longitudinal direction of the motorcycle or in the longitudinal direction of the trailing arm 9, 10, however, is ensured by the leaf spring-like elements 17, 18 a certain elasticity. To a certain extent, the joint receiving element 15 can therefore be displaced in the direction of the longitudinal direction of the trailing arm arms 9, 10. To a certain extent, a rotation of the joint receiving element 15 about a transverse axis, which is parallel to a transverse axis through the bearing eyes 11, 12, relative to the upper trailing arm 7 is possible.

Wie aus Figur 1 ersichtlich ist, ist in das Gelenkaufnahmeelement 15 ein Lagerzapfen eines oberen Kugelgelenks 20 eingesetzt. Über das obere Kugelgelenk 20 ist der obere Bereich des Radträgers 1 gelenkig mit dem oberen Längslenker 7 verbunden.How out FIG. 1 it can be seen, a journal of an upper ball joint 20 is inserted into the joint receiving element 15. About the upper ball joint 20, the upper portion of the wheel carrier 1 is pivotally connected to the upper trailing arm 7.

Der untere Längslenker 8, der in Figur 1 nur teilweise zu sehen ist, kann im Wesentlichen gleich gestaltet sein, wie der obere Längslenker 7. Im vorderen Bereich ist auf der untere Längslenker 8 über ein Kugelgelenk 21 mit dem Radträger 1 oder genauer gesagt mit dem Quersteg 6 des Radträgers 1 gelenkig verbunden.The lower trailing arm 8, the in FIG. 1 can only be partially seen, can be designed substantially the same as the upper trailing arm 7. In the front area is on the lower trailing arm 8 via a ball joint 21 with the Wheel carrier 1 or more precisely articulated to the cross bar 6 of the wheel carrier 1.

Figur 3 zeigt eine im Detailzeichnung des oberen Längsträgers 7 mit eingesetztem Kugelgelenk 20. FIG. 3 shows a detailed drawing of the upper longitudinal member 7 with inserted ball joint 20th

Figur 4 zeigt einen Längsschnitt durch den oberen Längsträger 7. In dieser Darstellung ist das Kugelgelenk 20 im Detail zu sehen. Das Kugelgelenk 20 weist einen Gelenkzapfen 22 auf, der mit einer Gelenkkugel 23 verbunden ist. Die Gelenkkugel 23 wiederum ist in eine Gelenkpfanne 24 eingesetzt. Die Gelenkpfanne 24 ist in eine zugeordnete Gewindebohrung eingeschraubt, die im oberen Bereich des Radträgers 1 (Figur 1) vorgesehen ist. FIG. 4 shows a longitudinal section through the upper side member 7. In this illustration, the ball joint 20 can be seen in detail. The ball joint 20 has a pivot pin 22 which is connected to a ball joint 23. The joint ball 23 in turn is inserted into a socket 24. The socket 24 is screwed into an associated threaded hole in the upper region of the wheel carrier 1 (FIG. FIG. 1 ) is provided.

Der Gelenkzapfen 22 ist in das Gelenkaufnahmeelement 15 (vgl. auch Figur 2) eingesetzt und mittels einer Sicherungsmutter 25 gesichert.The pivot pin 22 is in the hinge receiving element 15 (see also FIG. 2 ) and secured by a lock nut 25.

Die durch den vorderen und hinteren Quersteg 13 bzw. 14 gebildete Ausnehmung weist ein "gewisses Übermaß" in Bezug auf den Außenumfang des Gelenkaufnahmeelements auf. In den dazwischen verbleibenden Ringspalt ist ein Elastomer 26a, 26b eingesetzt. Hierbei kann es sich um zwei halbringförmige Elastomerelemente handeln, zwischen denen seitlich die beiden blattfederartigen Elemente 17, 18 herausragen. Die blattfederartigen Elemente 17, 18 sind dann, entsprechend dem Ausführungsbeispiel der Figur 2 mit dem Gelenkaufnahmeelement 15 verbunden.The recess formed by the front and rear transverse webs 13 and 14 has a "certain excess" with respect to the outer circumference of the joint receiving element. In the remaining annular gap between an elastomer 26a, 26b is used. This may be two semi-annular elastomer elements between which the two leaf spring-like elements 17, 18 project laterally. The leaf spring-like elements 17, 18 are then, according to the embodiment of FIG. 2 connected to the hinge receiving element 15.

Figur 5 zeigt eine Detaildarstellung des Gelenkaufnahmeelements 15 mit eingesetztem Kugelgelenk 20. Wie aus Figur 5 ersichtlich, weist das Gelenkaufnahmeelement 15 seitliche Schlitze 27, 28 auf, in welche die blattfederartigen Elemente 17, 18 eingesetzt sind. Die blattfederartigen Elemente 17, 18 können mit dem Gelenkaufnahmeelement vernietet, verschraubt oder in sonstiger Weise verbunden sein. FIG. 5 shows a detailed view of the joint receiving element 15 with inserted ball joint 20. As out FIG. 5 can be seen, the joint receiving element 15 has lateral slots 27, 28, in which the leaf spring-like elements 17, 18 are used. The leaf spring-like elements 17, 18 can be riveted to the joint receiving element, screwed or connected in any other way.

Figur 6 zeigt eine Detaildarstellung des Gelenkaufnahmeelements 15 von der Seite her gesehen. Deutlich zu erkennen sind in dieser Darstellung die beiden Aufnahmeschlitze 27, 28 zur Aufnahme der beiden blattfederartige Element 17, 18. FIG. 6 shows a detailed view of the hinge receiving element 15 seen from the side. Clearly visible in this illustration, the two receiving slots 27, 28 for receiving the two leaf spring-like element 17, 18th

Ausdrücklich sei nochmals darauf hingewiesen, dass sämtliche die Verbindung des oberen Längslenkers 7 mit dem Radträger 1 betreffenden Merkmale auch bei der Verbindung, die den unteren Längsträger 8 mit dem Radträger verbindet, vorgesehen sein können.It should be expressly pointed out that all the features relating to the connection of the upper trailing arm 7 to the wheel carrier 1 can also be provided in the connection which connects the lower longitudinal member 8 to the wheel carrier.
